T @ZZ whom t may concern:

Beit known that I, FRED W. HIRoNiMUs, a citizen of the United States,residing at Corydon, in the county of Henderson and State of Kentucky,have invented a new and useful Sash Balance and Lock, of which thefollowing is a specification.

The invention relates to improvements in sash balances and locks. j

[o The object of the present invention is to improve the construction ofspring sash-balances and to provide a simple and efficient lock adaptedto fasten a window either open 0r closed or at any-adjustment and topre- I5 vent the same from being moved upward or downward by exteriorpressure.

The invention consists in the construction and novel combination andarrangement of parts, as hereinafter fully described, illuszo tratedinthe drawings, and pointed out in the claim hereto appended. i L

In the drawings, Figure l is an elevation of a portion of a windowprovided with a sash balance and lock constructed in accordance z 5 withthis invention. Fig. 2 is a vertical sectional view on line sa :c ofFig. 1. Fig. 3 is a similar view on line y y of Fig. 2. Fig. 4. is adetail perspective view of the locking device. Fig. 5 is a similar viewof a portion of 3o the casing, illustrating the construction of the stopfor engaging the handle of the locking device. i

Like numerals of reference designate corresponding parts in the severalIigures of the drawings.

l designates a casing mounted in a recess of a window-sash 2 and havinga windingshaft 3 mounted in it and disposed horizontally, and upon thewinding-shaft is mounted a spring-actuated gear-wheel 4.., Thegearwheel, which is connected with the windingshaft by a clutch of theordinary construction, is connected with one end of a barrelspring 5,which has its other en d secured to the casing and which is designed totake the place of a sash-weight in balancing the sash. `Thespring-actuated gear-wheel meshes with a pinion 6 of a shaft 7, whichalso carries a cog-wheel 8, andthe latter engages a rack- 5o bar 9 ofthe window-frame 10, and the raising and lowering of the sash winds andunwinds the spring, as will be readily apparent. VThe clutch, whichconnects the spring-actuated gear-wheel tothe winding-shaft, operates inthe ordinary manner and enables the spring to be wound up to the propertension for balancing the sash, and after the spring has been adjustedto the proper tension it does not require any further attention.

The sash, which is designed to be provided 6o at each side with asash-balance, is locked at anydesired adjustment by a locking device 11,consisting of a crank-loop disposed transversely of the casing and journaled at its ends thereon. The crank-loop is adapted to engage thecog-wheel, and its engaging portion is substantially triangular incross-section to fit the spaces between the teeth of the wheel, which isheld against rotation in either direction. The outer end of thecrank-shaft is eX- 7o tended through the casing and has a handle 12secured to it and arranged on the faceplate of the casing, which isprovided with a p protuberance 13, forming a stop to lock the handleagainst upward movement and thereby retainthe locking device inengagement with the cog-wheel. The protuberance forms a shoulder at oneside and a beveled face at the other side, and it effectually preventsthe locking device from being thrown out of en- 8o gagement with thecog-wheel by shaking or j olting the sash.

It will be vseen that the sash balance and lock is adapted to be readilyapplied to any ordinary window, that it will' take the place 85 ofsash-weights and sash-fasteners, and that the locking device is adaptedto securely liasten asash either closed or at any desired adjustment,and that it cannot be'thrown out of engagement with the cog-wheel byjarring 9@- or `jolting the windowsash- In a device of the classdescribed, the com` bination with a window-frame having a racky bar, anda sash, of a spring-actuated cogwheel mounted on the sash and meshingwith the rack-bar, a crank-loop j ournaled in suitable bearings andarranged to swing into and out of engagement with the .teeth of thecogwheel and having one end or journal extended roo through theWindow-sash, a easing or plate A mounted on the sash and provided with aprotuberanee 13 struck up from the metal of the easing or plate andhaving a beveled face at one side and a shoulder at the other, and a fhandle arranged on the exterior of the plate or easing and secured t0the extended end or journal of the crank-loop, said handle beingarranged to swing into and out of engage-
